About Us

Cardinal Air

We've been a family owned company since 1996. My sons have learned the service and the business first hand from me and then received formal educations to solidify all that they've learned. Our staff are all dedicated professionals that are here to serve you. Over the years, we have gone from a small business to one of the area's most well trusted and reliable air conditioning and heating companies. Customer satisfaction is our main goal and even during our busiest times, your comfort is our main concern.

In the field of commercial service, we have been the backbone of many businesses that rely on our knowledge and prompt service. In the residential field, we have almost all repeat customers because of our friendly and reliable service.
